Ezekiel 43:16-18 Tree of Life Version (TLV)
16 The hearth will be 12 cubits long by 12 wide, with four sides square. 17 The ledge will be 14 cubits long and 14 wide with four sides square. The border surrounding it will be half a cubit and its bottom will be a cubit all around. Its steps will face east.”
